WASHINGTON — Doctors at a psychiatric hospital say a 20-year-old man charged with fatally stabbing a passenger aboard a Metro train is criminally responsible.

The Washington Post reports that (http://wapo.st/2rfU2Ot ) a judge on Friday read from a report by psychiatrics on Jasper Spires, who is accused of killing Kevin Sutherland in 2015.

The doctors say Spires may have suffered from mental illness, but that it wasn’t so severe that he should be found not criminally responsible. They found that Spires is now competent to assist his defense at trial.

Prosecutors say Spires stabbed Sutherland while trying to steal his cell phone.

Spires’ attorneys have said their client was mentally incompetent.

The judge has set a tentative trial date for May 2018.
